WebTrigonometry. Solve for x cos (2x)=-1. cos (2x) = −1 cos ( 2 x) = - 1. Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. 2x = arccos(−1) 2 x = arccos ( - 1) Simplify the right side. Tap for more steps... 2x = π 2 x = π. Divide each term in 2x = π 2 x = π by 2 2 and simplify. WebIt is indeed true that sin2(x) = 1−cos2(x) and that sin2(x) = 21−cos(2x). How do you use the half-angle identities to find all solutions on the interval [0,2pi) for the equation sin2x = cos2(2x) ? π,π and.π Explanation: Use cos a = cos2a . The given equation is sin2x = cos2x = 1− (2cos2(2x)−1)2 = cos2(2x) ... WebMar 30, 2024 · Transcript.
